ISP847D Equivalent & Substitute Parts

Part Overview

The ISP847D is a quad-channel optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This 16-pin DIP component provides galvanic isolation up to 5300Vrms across four independent channels, each capable of 50mA output current. The device is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the ISP847 series, ensuring direct functional interchangeability in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISP847D are identified within the ISP847 series based on strict parametric equivalence. All substitute candidates maintain identical electrical specifications across the following critical parameters: 4-channel configuration, 5300Vrms isolation voltage, 300-600% current transfer ratio at 5mA, 35V maximum output voltage, 50mA per-channel output current, 200mV maximum Vce saturation, and 4µs/3µs rise/fall times. All substitutes share the same 16-DIP through-hole package footprint, operating temperature range, and compliance certifications (RoHS3, REACH unaffected). Substitution is valid when circuit design requirements do not depend on specific packaging variants or supplier-specific device package designations.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (ISP847XD, ISP847XDG, ISP847XDSM) are functionally equivalent to the ISP847D based on identical electrical and mechanical parameters. Selection among these alternatives may be determined by inventory availability and supplier device package designation. All candidates maintain Active product status with full RoHS3 compliance and REACH unaffected classification, ensuring regulatory compliance across applications. The 16-DIP through-hole package is consistent across all variants, permitting direct PCB footprint compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can ISP847XD, ISP847XDG, and ISP847XDSM be used interchangeably with ISP847D?

A: Yes. All parts share identical electrical specifications including 5300Vrms isolation, 4-channel configuration, 300-600% current transfer ratio, 50mA output current per channel, and 200mV maximum Vce saturation. The 16-DIP through-hole package footprint is identical across all variants.

Q: What determines substitution eligibility for ISP847 series optoisolators?

A: Substitution is valid when the candidate part maintains the same number of channels (4), isolation voltage (5300Vrms), current transfer ratio range (300-600% @ 5mA), maximum output voltage (35V), per-channel output current (50mA), Vce saturation (200mV), and package type (16-DIP through-hole). All listed substitutes meet these criteria.

Q: Are there differences in packaging or supplier device package designations?

A: The supplier device package designation for all parts is 16-DIP. Differences in part number suffixes (D, XD, XDG, XDSM) reflect internal manufacturer coding but do not alter electrical performance or physical footprint compatibility.

Q: Do all substitute parts have the same compliance certifications?

A: Yes. ISP847D, ISP847XD, ISP847XDG, and ISP847XDSM are all RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the operating temperature range for these optoisolators?

A: All ISP847 series variants operate across -30°C to 100°C, ensuring consistent thermal performance across substitute selections.
